USG20-VPN low internet LAN speed comparing to WAN

toxstoxs

Hi.

I'm experiencing a strange issue with that FW.

The internet connection speed took from Fiber line router is about 850 Mbit/sec (1Gbit contract).

Looking at the FW control panel, the LAN1 connection is regularly negotiated at 1000M (1Gbit) but the internet speed is capped at 400/420 Mbit.

No way to get the 850 that router can provide.

Is there any kind of hidden speed control i can't see in FW control panel?

Hi @toxstoxs,

In datasheet, the USG20-VPN performance is around 350~400 Mbps.
We would suggest swap to ATP or FLEX series for better performance.
